Pivotable Coupling Assembly with Lateral Flexure
Abstract
A pivotable coupling assembly having lateral flexure and
apparatuses utilizing the pivotable coupling assembly. The
pivotable coupling assembly includes a link that is adjustably
connected to a first member, such as a board, and a yoke that is
connected to a second member, such as a base. The yoke is
configured to pivotably receive the link, allowing the first member
to pivot longitudinally relative to the second member. The link is
fabricated from a material having sufficient stiffness to support
the weight of a board and a rider, while also having sufficient
flexure to allow the link to bend laterally when stressed. The
pivotable coupling assembly thereby allows the first member to
rotate or bend laterally, while still permitting longitudinal
movement thereof. The bidirectional movement provided by the
coupling assembly mimics the movement or control of a board, such
as a snowboard, under normal conditions when snowboarding.

Description
BACKGROUND OF THE INVENTION
[0001] The present invention relates to pivotable coupling
assemblies. More specifically, the present invention relates to
pivotable couple assemblies that are configured to provide
bidirectional, i.e. both longitudinal and lateral, movement between
two coupled components.
[0002] It can be difficult for beginner snowboarders to control
their body movements while strapped into a snowboard, making it
especially troublesome to exit a chairlift. Even advanced and
professional snowboarders must refine and improve their technique
to r raster their craft. Snowboarders require a specific amount of
balance and riders need to know how to shift their weight along
different points of the device. Therefore, there exists a need for
a device that can assist both novice and seasoned snowboarders to
train for snowboarding.
SUMMARY OF THE INVENTION
[0003] In view of the disadvantages inherent in the known types of
board training apparatuses now present in the prior art, the
present invention provides a pivotable coupling assembly that is
configured to both pivot longitudinally and flex laterally, thereby
improving devices used for training for snowboarding,
skateboarding, wakeboarding, and other such board or board-related
sports. The present invention comprises a pivotable coupling
assembly having lateral flexure and apparatuses utilizing the
pivotable coupling assembly. The pivotable coupling assembly
includes a link that is adjustably connected to a first member,
such as a board, and a yoke that is connected to a second member,
such as a base. The yoke is configured to pivotably receive the
link, allowing the first member to pivot longitudinally relative to
the second member. The link is fabricated from a material having
sufficient stiffness to support the weight of a board and a rider,
while also having sufficient flexure to allow the link to bend
laterally when stressed. The pivotable coupling assembly thereby
allows the first member to rotate or bend laterally, while still
permitting longitudinal movement thereof. The bidirectional
movement provided by the coupling assembly mimics the movement or
control of a board, such as a snowboard, under normal conditions
when snowboarding.

DETAILED DESCRIPTION OF THE INVENTION
[0012] Reference is made herein to the attached drawings. Like
reference numerals are used throughout the drawings to depict like
or similar elements of the pivotable coupling assembly with lateral
flexure. The figures are intended for representative purposes only
and should not be considered to be limiting in any respect.
[0013] Referring now to FIG. 1, there is shown a perspective view
of an embodiment of the coupling assembly as utilized in a
snowboard training apparatus. The present coupling assembly is
demonstrated in use as with a snowboard training apparatus in order
to provide context; however, it should not be interpreted as
limiting in any way. The present coupling assembly is configured
for use with a training apparatus for any type of board sport, e.g.
wakeboarding and skateboarding, and may additionally be
incorporated into an apparatus configured for actual use in the
field, rather than simply training.
[0014] The depicted snowboard training apparatus includes a board
101 connected to a base 102 via at least one pivotable coupling
103. The board 101 has the shape and configuration of a
conventional snowboard. In one embodiment, the base 102 has a
planar bottom surface that allows the apparatus to rest flat
against a support surface when in use. In alternative embodiments,
the board 101 is a skateboard deck, a wakeboard, or any other such
device utilized in board sports. In one embodiment, the board 101
further includes bindings configured to engage snowboard boots,
integrated boots configured to receive and bind the feet of a
wearer as in a wakeboard, or other such supports. Alternatively,
the board 101 lacks any bindings thereon.
[0015] In alternative embodiments, the base 102 is itself a second
board, e.g. snowboard or skateboard deck. In these embodiments of
apparatuses using the present pivotably coupling assembly, the base
102 and the board 101 are arranged in a stacked configuration
wherein the user controls the movement of the apparatus by
manipulating the board 101, which in turn controls the movement of
the base 102 relative thereto. This configuration wherein the base
102 is a second board can be utilized in all types of board sport
applications.
[0016] The pivotable coupling 103 is configured to pivot in a
longitudinal direction and flex or bend in a lateral direction. The
longitudinal direction is measured from a first end of the board to
the second end of the board, wherein the lateral direction is
perpendicular thereto. In embodiments of apparatuses configured to
be utilized as training apparatus for conventional boards, the
pivotable coupling 103 mimics the movement commonly associated with
different types of board sports in order to allow users to practice
balancing and other techniques utilized when partaking in these
sports on a training apparatus. In embodiments of apparatuses
configured to be utilized in the field during sporting
applications, the pivotable coupling 103 allows for indirect
control of the underlying base 102 via manipulation of the board
101, while still providing the board 101 with properties that mimic
the feeling of directly controlling such a snowboard, skateboard,
wakeboard, or other such sports board apparatus. Additionally, in
alternative embodiments of apparatuses utilizing the present
pivotable coupling assembly, the board 101 is a first type of
board, e.g. a skateboard deck, and the base 102 is a second type of
board, e.g. a wakeboard. This allows users to modify the base type
of board with another type of board that the user ay be more
familiar with or may simply prefer, while still allowing them to
undertake the activity for which the base type of board was
designed.
[0017] Referring now to FIG. 2, there is shown an exploded
perspective view of an embodiment of the coupling assembly as
utilized in a snowboard training apparatus. Each pivotable coupling
103 includes a first yoke 201 and a second yoke 204, wherein the
first yoke 201 is disposed on the upper surface of the base 102
that is configured to engage the lower end 217 of a link 202
disposed on the lower surface of the board 101. The upper end 218
of each link 202 is secured to the undersurface of the board 101
via the second yoke 204. In the illustrated embodiment, each yoke
201, 204 includes at least one groove 208. In the illustrated
embodiment, each yoke 201, 204 comprises a pair of grooves 208 that
are configured to receive a pair of links 202 therein. Each groove
208 is configured to receive a single link 202. The link 202 is
joined to the yokes 201, 204 via fasteners 205 extending through
apertures disposed in the links 202 and grooves 208. A groove 208
has a width approximately equal to the width of a link 202, thereby
restricting the link 202 from laterally reciprocating along the
fastener 205 within the groove 208 when the link 202 is engaged
with the yoke 201, 204. The angle at which the link 202 can pivot
about a vertical axis is restricted by a pair of restrictors 216
that are positioned centrally between the yokes 201, 204. The lower
restrictor 216 is secured to the first yoke 201 and the links 202
by a lower fastener 205 and the upper restrictor 216 is secured to
the second yoke 204 and links 202 by an upper fastener. Further,
the restrictors 216 are configured to prevent the fasteners 205
from disengaging from the links 202.
[0018] The upper end of each link 202 is securable to the second
yoke 204 in one of multiple different positions, e.g. a posterior
position relative to the second yoke 204, a neutral position
relative to the second yoke 204, and an anterior position relative
to the second yoke 204. In an illustrative embodiment of the
pivotable coupling assembly 103, the link 202 includes a plurality
of apertures 214A, 214B, 214C extending along its first end 218.
When the link 202 is joined to the second yoke 204 via a fastener
205 through a first aperture 214A, the link 202 is positioned
posteriorly relative to the second yoke 204. When the link 202 is
joined to the second yoke 204 via a fastener 205 through a second
aperture 214B, the link 202 is positioned neutrally relative to the
second yoke 204. When the link 202 is joined to the second yoke 204
via a fastener 205 through a third aperture 214C, the link 202 is
positioned anteriorly relative to the second yoke 204. The
adjustable coupling of the link 202 to the yoke 201 allows users to
adjust the properties.
[0019] Referring now to FIG. 3, there is shown of an exploded view
of a first embodiment of the coupling assembly. The links 202 are
joined to the yoke 201 via the fastener 205 extending through
aligned apertures disposed in the link 202 and each side of the
groove 208. In the illustrated embodiment, the fastener 205 is an
elongated pin having a pair of distal ends 219 and a central
portion 220 disposed therebetween. In the illustrated embodiment,
the central portion 220 comprises a diameter that is smaller than
the diameter at the distal ends 219.
[0020] In one embodiment, the width of the link 202 tapers from the
upper end 218 to a rounded lower end 217. This tapered, rounded
second end 213 allows the link 202 to rotate within the groove 208
along the longitudinal axis thereof until the restrictor 216
contacts a second restrictor 216 or the lower face of the board
101. The lower end 217 further includes an aperture 209 thereon.
The aperture 209 of the link 202 is positioned so as to align with
a corresponding aperture 210 disposed on the first yoke 201 when
the link 202 is engaged with the yoke 201. A fastener 205, such as
a pin in the depicted embodiment of the snowboard training
apparatus, can then be inserted through the aligned set of
apertures 209, 210 to pivotably couple the link 202 to the yoke 201
about the fastener 205. When pivotably coupled, the board 101 is
able to pivot longitudinally relative to the base 102. The degree
of rotation of the board 101 relative to the base 102 is determined
by the length of the groove 208.
[0021] Each restrictor 216 comprises a slot 221 configured to
receive the central portion 220 of the fastener 205. The slot 221
extends from the lateral sides of the restrictor 216 and comprises
a width that is slightly smaller than the diameter of the central
portion 220. The width of the restrictor 216 is measured from the
lower side 223 to the upper side 224 thereof. In this way, force is
required to secure the restrictor 216 to the fastener 205. The slot
221 is adapted to open wider as the central portion 220 is forced
from the distal end of the slot 221 to the proximal end. The
proximal end of the slot 221 comprises a notch 222 that receives
the central portion 220 of the fastener 205 therein. In the
illustrated embodiment, the notch comprises a circle shaped
cross-section. When the central portion 220 is disposed within the
notch 222, the slot 221 returns to its natural or biased position
and the fastener 205 is secured within the restrictor 216 until
force is applied to open the slot 221 to a wider orientation. The
end of the restrictor 216, opposing the distal end of the slot 221,
comprises a ring 231 configured to receive a finger therethrough.
The ring 231 assists the user when applying force to secure and
unsecure the restrictor 216 to the fastener 205.
[0022] Referring now to FIG. 4, there is shown a front view of a
first embodiment of the coupling assembly in an alternate
configuration. In an alternate configuration of the coupling
assembly, the links 202 are disposable within a central groove 232
of each yoke 201, 204. The central groove 232 is dimensioned to
receive a pair of links 202 in a side-by-side orientation. The
grooves 208 positioned on opposing sides of the central groove 232
are each configured to receive a single link 202 therein. The links
202 rest flush against the sides of the grooves 208, 232 when
positioned therein. A distal end of a fastener 205 is positioned
through apertures within links 202. A restrictor 216 receives the
central portion of the fastener 205 therein. This positioning of
the links 202 within the central groove 232 allows the board more
lateral movement relative to when the links are positioned within
the outer most grooves 208.
[0023] Referring now to FIG. 5, there is shown the front view of
the first embodiment of the coupling mechanism. The links 202 are
fabricated from a material that has sufficient stiffness to support
the weight of the board and a rider thereon, but sufficient flexure
to allow the link 202 to bend or deform laterally when subjected to
the force of a rider manipulating the board 101. The ability of the
link 202 to bend under sufficient stress, but then elastically
return to its set position when the stressing force is removed
allows an apparatus utilizing the present pivotable coupling
assembly to mimic the movement and control of a conventional board,
e.g. a snowboard. In one embodiment, the links 202 are fabricated
from urethane 60D. In another embodiment, the links 202 are
fabricated from urethane 75D. The links 202 may be constructed via
injection molding of any such process. In another embodiment, the
links 202 are fabricated from a material that maintains the
aforementioned stiffness and elasticity properties at sub-freezing
temperatures and/or while exposed or submerged in water so that the
links 202 are suitable for use in snowboarding, wakeboarding or
other such applications.
[0024] In the illustrated embodiment, the resting state of the link
202 is in an upright, linear orientation. When lateral force is
applied to the link 202 via the tipping or manipulation of the
board, the upper end of the link 202 bends or flexes along the same
side as the board movement. The second restrictor 216 moves along
with the board and upper end of the link 202. When the second
restrictor 216 contacts the first restrictor 216, the link 202 is
prevented from further lateral movement toward the base.
[0025] Referring now to FIG. 6 there is shown a second embodiment
of the coupling assembly as utilized in a skateboarding training
apparatus. In a second embodiment, the coupling assembly comprises
500 a first yoke 501 having a groove 502 centrally disposed
thereon. The first yoke 501 is secured to a pair of wheels 503 via
a fastening mechanism 504, wherein the wheels 503 are positioned on
the distal ends of the first yoke 501. A lower end of a link 505 is
disposed within the groove 502, wherein an upper end of the link
505 is secured to a second yoke 508 having a central groove 509.
The upper end of the link 505 comprises an aperture that is aligned
with an aperture disposed on each side of the central groove 509 of
the second yoke 508. A fastener 510 is disposed through the
apertures in order to secure the link to the second yoke 508. The
second yoke 508 is securable to an underside of a board, such as a
skateboard.
[0026] Referring now to FIG. 7, there is shown a perspective view
of a carrying accessory disposed around a first embodiment of the
coupling assembly. In some embodiments, the present invention
comprises a carrying accessory 311 adapted to secured to the
coupling assembly 103. The carrying accessory 311 comprises at
least a pair of pouches, wherein a first pouch 312 is adapted to
rest along a first lateral side of the coupling assembly 103 and a
second pouch 313 is adapted to rest along a second lateral side of
the coupling assembly 103. Each pouch 312, 313 is adapted to hold
personal items therein. A first strap 314 permanently connects
adjacent ends of the pouches 312, 313 to one another, wherein the
first strap 314 is adapted to wrap around a front end of the
coupling assembly 103. A pair of second straps 315, 316, each
extending from opposing sides of the pouches 312, 313, are
configured to fasten to one another, such that the carrying
accessory forms a loop around the coupling assembly 103. In some
embodiments, a leash is rotatably secured to the board via a ball
bearing so as to allow a user to secure the board to his or her
person via the leash.
[0027] It is therefore submitted that the instant invention has
been shown and described in various embodiments. It is recognized,
however, that departures may be made within the scope of the
invention and that obvious modifications will occur to a person
skilled in the art. With respect to the above description then, it
is to be realized that the optimum dimensional relationships for
the parts of the invention, to include variations in size,
materials, shape, form, function and manner of operation, assembly
and use, are deemed readily apparent and obvious to one skilled in
the art, and all equivalent relationships to those illustrated in
the drawings and described in the specification are intended to be
encompassed by the present invention.
[0028] Therefore, the foregoing is considered as illustrative only
of the principles of the invention. Further, since numerous
modifications and changes will readily occur to those skilled in
the art, it is not desired to limit the invention to the exact
construction and operation shown and described, and accordingly,
all suitable modifications and equivalents may be resorted to,
falling within the scope of the invention.
